Is this connection correct?

My Contractor installed the drain-tile adapter inside the gutter downspout. Please see the picture.
Norman Nowling from Landscape Design and Property Development in Fort Myers, FL says: "The manner it's installed is correct. Think about the design; if you were to install the downspout inside the adapter, any debris falling downward (leaves, sticks, dirt etc) would be able to fall into the ADS pipe and clog it. That is why the gutter fits outside the adaptor. During a torrential downpour, no gutter system is able to keep up or accomodate the exessive run off. The volume of water coming down the gutters exceeds the rate the ADS pipe can dispurse the water through the tube and out the other end. However, it is still doing 90% of the work by routing the water away from your foundation, even in a heavy downpour. You will notice in a light, or normal rain the pipe doesn't have any run-off. I assure you there is no better alternative."
I think Norman is wrong and lying to me. What do you think?
The drain-tile ends further out in the yard with a pop-up fitting. The intention was to get the water away from the house and walk way. I can't find any other picture on the web with the down-spout is on the outside of the adapter. The gutter is always on the inside.

I feel your correct and he's wrong, but it's nothing but a slip fit so either way if that tile is not installed correctly with enough slope, open to day light on the far end, not under water in a ditch where the water can not exit any over flow is still going to back up and flow out that fitting.

I never seal up that fitting, that way if the down spout plugs up it's simple to remove and clean out.

That is NOT the correct way to install that - evidenced partly by the fact that it is NOT working properly!
